Drug delivery research areas is continuously broaden and modified as a results of the realization of many factors (such as poor drug solubility and/or absorption, rapid metabolism, high fluctuation in the drug plasma level and variability) adversely affect in-vivo results, in conventional drug delivery system. Lipids are one of the basic building blocks of biological membranes. Nanoscale-based ...

conclusions carriage of pvl-positive s. aureus is common in this region, even in the low frequency of mrsa colonization. the detection of acme-arca gene in s. aureus isolates is a public-health concern and demands continued surveillance and close monitoring. results among the 813 subjects screened, 83 (10.2%) were persistent carriers, 86 (10.6%) were transient carriers and 644 (79.2%) cases wer...

delivery of exogenous materials such as nucleic acids, peptides, proteins, and drugs into cells is an important strategy in modern cellular and molecular biology. recently, the development of gene carriers for efficient gene transfer into cells has attracted a great attention. furthermore, lack of effective drug delivery is one of the major problems of cancer chemotherapy. many physical methods...

background and objective: staphylococcus aureus is an important infection in hemodialysis patients. we studied the prevalence of nasal carriage of methicillin-resistant staphylococcus aureus (mrsa) and its antibiotic resistance pattern in patients receiving hemodialysis as well as in dialysis unit staff. materials and methods: from june to september 2012, we evaluated 74 cases including 61 pati...

as one of the most important products of iran, pistachio has a significant share in non-oil revenues. its annual foreign exchange earnings are over 800 million dollars. however, production of this nut in the country’s major production centers is faced with many problems regarding the efficiency and productivity of the inputs. this study was performed by using two-stage cluster sampling method. ...
